GUSTAV BURKHARDT, OF HOMER, ILLINOIS.

WASHING- MACHINE.

SPECIFICATION fermizze part of Letters Patent No. 318,413, dated May19,1885.

Application filed May 8, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAV BURKHARDT, a citizen of the United States,residing at Homer, in the county of Ghampaign and State of Illinois,have invented new and useful Improvements in lVashingMachines, of whichthe following is a specification.

This invention relates to that class of washing-machines comprising arevolving clothes drum or cylinder; and it consists in the novelfeatures of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal section of awashing-machine embodying my invention. Fig. 2 is a horizontal sectionthereof in the plane of the line 00 at, Fig. 1. Fig. 3 is a detail viewof the drum.

Similarletters indicate corresponding parts.

The letter A designates the clothesdrum, which is supported in asuds-box, B, by means of gudgeons 0, one of which is provided with acrank-handle, I), for imparting a revolving motion to the drum. Theheads E of the drum are both provided on the outer surface with acircular range of sc ops, F, opening in like directions and with holes Gat points opposite to the scoops. so that if the proper motion isimparted to the drum air, together with the water in the suds-box, iscaught up by the scoops, and thence forced into the drum through theholes, thus percolating through the clothes in the required manner. Theheads E of the drum are conical in shape, thereby facilitating theoperation of the scoops, and are provided on the inner surface withradial ribs I, the inner edges of which are in theline of the base ofthe cone, as shown in Fig. 2, so that these ribs act on the clothes witha tendency to throw it outward toward the side of the drum. The side ofthe drum A is provided with transverse corrugations J, which tend tocarry the clothes upward, so that by On the bottom and sides of thesuds-box B is a waterjacket, L, and on one side thereof is a chamber, N,which communicates with the jacket, and through which passes aheating-flue, 0, so that if this chamber is supplied with water thewater thence flows into the jacket in a heated condition, therebywarmingthe water in the suds-box. The hot water may be let into the suds-boxfrom the jacket L through a hole in the bottom of the box, provided witha valve, S, and the height of the water both in the jacket and thesuds-box may be regulated by means of cocks R, connected to such parts,respectively. The heatingfiue O is provided with a firegrate, P, andashpan Q, so that a fire may be built in it, and the water-heatingchamber N is provided with a suitable lid.

IVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a washingmachina the combination, with a sudsbcx, of a closedrevolving drum having conical heads E, provided with holes G, and acircular range of buckets, F, secured to and projecting outwardly fromthe exterior surfaces of the drum-heads, for lifting up the suds fromthe box and discharging the same therefrom into the drum through theholes, and a series of radial ribs, I, secured to the under surfaces ofthe drum-heads with their inner edges approximately in line with thebase of the conical heads, substantially as described.

2. The combination of the suds-box, an outer jacket therefor 011 thebottom and part of the sides, a heating-chamber upon one sidecommunicating with the jacket, a heating device, substantiallysuch asdescribed, located mainly beneath the heating-chamber and part thereofpassing therethrough, a valve controlling communication between the sudsbox and the jacket, and closed revolving drum seated in the suds-box,substantially as described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
